Phytochemical Analysis, Radical Scavenging And Anti-Microbial Activity Of The Leaves Of Gomphocarpus Fruticosus

AbstractGomphocarpus fruticosus is a wild plant that belongs to the Asclepiadaceae family and has many traditional uses. The plant has demonstrated by this study a significant level of microbial and phytochemical activity; the drug-resistant strains of microbes which have emerged in the last decade will be eradicated by the compounds this indigenous plant carries. This particular study aimed to scientifically validate the traditional uses of the plant G. fruticosus. The objectives of this stu...

Qualitative and Quantitative Determination of Phytochemical Contents of Indigenous Nigerian Softwoods

ABSTRACTThe phytochemical contents of some milled Nigerian softwood chips were carried out in a quest to evaluate their potentials as sources of alternative medicine as well as uses in other industrial applications. The qualitative and quantitative analysis were ascertained. Tannin was found in all the Nigerian softwoods examined with the highest quantities obtained in Sterculia oblonga (1240 mg/100 g) and Barteria nigritiana (1230 mg/100 g). Highest quantities of alkaloid were obtained in...

EFFECT OF FOOD CHAIN MEDIATED CHRONIC EXPOSURE TO ARSENIC AND CADMIUM ON REDUCED GLUTATHIONE (GSH) AND GLUTATHIONE S￾TRANSFERASE (GST) LEVELS IN THE BRAIN OF ALBINO RAT (WISTAR RAT)

ABSTRACTThe study aims to evaluate the effect of food chain mediated chronic exposure to arsenic and cadmium (singly and combined) on the level of reduced glutathione (GSH) and the activity of glutathione S-transferase (GST) in brains of rats. Fortymale Wistaralbino rats were fed with a diet containing fish fed with normal feed in water contaminated with 0.4 mg/100 ml cadmium (group B), arsenic (group C) and cadmium + arsenic (group D) respectively for three months. The control rats were...

Methodology:  The  fruits  of  Xylopia  aethiopica  were  air-dried  and  extracted  using  Soxhlet apparatus  and  ethanol  ...

Hybridoma Technology

  INTRODUCTION: Hybridoma technology is a method for producing large numbers of identical antibodies (also called monoclonal antibodies ). This process starts by injecting a mouse (or other mammal) with an antigen that provokes an immune response. A type of white blood cell, the B cell, produces antibodies that bind to the injected antigen. These antibody producing B-cells are then harvested from the mouse and, in turn, fused with immortal B cell cancer cells, a myeloma ,  to prod...

Garlic Bulb Prevents High Blood Pressure in Egg Yolk induced Hypertensive Rats

The aim of this study is to access the antihypertensivepotential of garlic juice in rats. To achieve this, 30 Wistar ratswere divided into three groups of 10 each. Rats in groups 1 and 2received aspecial prepared egg feed diet (24 egg yolkmixed with 1kg of normal rat diet) while those in group 3 received normalfeed diet and they served as the control group. Animals in group2 were administered 3 mL/100g body weight of undiluted garlicjuice simultaneously with the feeding. The animals were fedo...

Egg Yolk induces High Blood Pressure in Wistar Rats

Hypertension constitutes a major risk factor forseveral cardiovascular diseases such asatherosclerosis, heart failure, renal insufficiency,coronary artery disease and stroke. The risk factorincreases with age in both sexes. According to WHO,about one-third of the world’s population suffersfrom hypertension and the incidence has beenincreasing at a rapid rate due to life stylemodification. This study is aimed at investigating theeffect of egg yolk on blood pressure of Wistar rats. Toachieve ...

Effect of Consumption of Garri Processed by Traditional and Instant Mechanical Methods on Lipid Profile of Wistar Rats

Aim: This study focuses on the effect of consumption of garri processed by traditional and instantmechanical methods on the lipid profile of Wistar rats.Methods: Cassava samples were obtained from the International Institute of Tropical Agriculture(IITA), Ibadan and were processed using traditional and instant mechanical methods. Fifteen adultmale Wistar rats were purchased from the Animal Holding Unit of the Department of Physiology,University of Ibadan, Nigeria with body weight between 100 ...

Air Freshener induced Oxidative Stress and Adveresly affects Immunity

Recently, the use of ‘sunlight’ air freshener in Nigeria is on the increase. Some people use airfreshener in the office, car as well as in their homes, thereby constantly being exposed to it withoutconsideration of its adverse effect on human health. This study is therefore aimed at assessing theeffect of “sunlight” air freshener on oxidative stress biomarkers. Thirty (30) Wistar rats were dividedinto three groups of ten each and kept in different rooms. Rats in group 1 were not expos...

Effect of Common Household Insecticides Used in Nigeria on Rat Male Reproductive Hormones

Background: The use of household insecticides for the eradication of insects especially mosquitoesin Nigeria is increasing. These insecticides are used without consideration of their adverse effect onhuman health.Aim: This study was aimed at accessing the effect of common household insecticides used inNigeria on male reproductive hormones of Wistar rats.Methodology: Thirty male Wistar rats were divided into five groups of six each and kept in differentrooms. Rats in group 1 were exposed to Ra...

Consumption of Coconut (CocosnuciferaL.) WaterImproved Fertility Parameters in Male Wistar Rats

Background: The need for fertility stimulation in men and women cannot be overemphasizedespecially when a marriage is childless in some communities in Nigeria. While chemical methodsfor fertility stimulation may have some side effects and are not readily available, remedy fromnatural sources can be used.Aim: This present study is aimed to evaluate the effect of coconut water on fertility in male Wistarrats.Materials and Methods: Coconuts of about 8 months old were harvested from Apata area of...
